Is the nikon d610 good in low light?

Yes, the D610 is a good low-light body for its money. It's a full frame camera, and a bigger sensor collects more light at the same framing and f-number, so images stay cleaner at high ISO. I'd say it's about a stop ahead of an APS-C camera. The body has no stabilisation, so for slow shutter speeds, pick a stabilised lens. For dim scenes, I'd pair it with a fast prime like the Nikon AF-S 50mm f/1.8G, the Sigma 35mm f/1.4 DG HSM Art, or the stabilised Nikon AF-S 24-70mm f/2.8E ED VR for a flexible zoom.
